You do know that the 7th injector IS a fuel mod don't you? Not as complete as the URD kit but better than nothing for sure.

BTW probably 99% of the people on this board DO care about their engine lasting past the warranty.

 

Why would you SELL a vehicle in THAT condition?

 

I have simply changed my mind. I don't feel I need either kit at this time. I know that is a tough concept for many people here to grasp but it is what it is I invite anyone in san diego area to see how well the truck runs SC'd only, its just fine.

Of course I care about the truck lasting longer than the warraty, but at that point, repairs are on me, and I rather sell the truck and only dump more money into the 4runner (140K miles currently with no warranty). BTW, I take great care of my cars, I just sold an 11 year old chevy truck in perfect condition with only 94K on it, I was original owner. Who knows maybe I will keep the tacoma for longer than 5-6 years, but if my engine is in as bad of shape as everyone thinks it will be, then that is another story.

 

URD has quite a few spark plugs on their site, which ones are the ones that come with the fuel upgrade kit? Thanks in advance!

Hey Sean, mine came with the Denso IK22.

 

I just wanna add my 2 cents.

You are modifying a 5VZFE. With this I mean you could boost it 10 psi if you wanted to and WOT it every single second of it's life and run it safer than it could ever be stock.

How far you wanna go is up to you, and that means that anything that goes wrong is your fault because you theoretically COULD mod it to last just as long as stock.

I don't know why, I just felt like saying this, so people who want the power and are willing to spend the $$$ don't get shyed away.

 

cool, thanks

 

EDIT: That's for a 1996-1997 3.4L right?

 

Yes, you'll want the IK22's.

fwiw, I picked up a set from eBay for less than URD sells them for.

 

Has anybody tried 1 step colder than the IK22's yet? I'm thinking about it.

 

Yeup... I ran IK20's for about a year. I had a ping issue under load so I figured I'd move to the 22's this time. They helped...

I can't tell if there's a loss of power or not, I guess in theory there should be, but it's not noticable.

 

I was thinking more like IK24's

 

OH! sorry... I misread your original post. You want to go COLDER than 22's.

yes, you're right.. IK24's.

 

My kit was for a 2001 5VZFE.

 

I kept meaning to bring this up, but I only just now remembered.


Christian touched on this, but while you can "hear" ping (though not all pinging will be audible) you can't really tell if the engine's running lean in open loop without instruments.

There are two issues running a stock fuel/timing system with a S/C on these engines. Low RPM ping, and High RPM lean. You're convinced that ping isn't an issue for you, but you really should look for a way to figure out if you're running lean. Even a cheap A/FR meter will help - you don't need wideband to see the lean-out up top.

 

you can run supra 7mge injectors for the SC right?
if so are they a direct fit for the stock rail?

also couldnt your setup consist of the SC and all related mechanical parts, plugs, injectors, 190walbro, and an Apexi AFC?
im wondering why you need to spend so much on the URD tuning calibration unit thing?

is it like a semi-standalone? or what, because im a honda car guy, and have seen too many 20+ psi boosted hondas running only an afc and an FMU.
not the best setup, but when run down at lower boosts it can be reliable.

Funny you should ask.

I have a set of 7MGTE's right here, tried to fit one on Sunday and while the top fit the rail just fine, the barrel's too big for the port in the cylinder.

 

port in the cylinder? or the manifold?
you can just bore the holes some im assuming. thats what honda people do a lot.
take a pic and ill let you know.

Manifold... sorry.

It's not worth it to me to start modifying my intake manifold to make this happen. I'd be sooner to spend the $500 with Gadget to get a set of RC's that have the shoulder milled down. ...which ain't gonna happen either.

The problem is the unknown of being able to actually tune the 440's for idle. It's one thing for me to spend the time to drop them in, fight tuning, give up, then replace them with the 305's I'm running, but if I drill out the manifold, I'll never get the 305's back in.

What I'm actually in the market for now is a set of milled 370's. I know I can idle those, and they'll be "fine" at getting fuel in there to the point I'm taking the engine.

 

the tuning brings me back to my ? about an AFC...
